That is the same exact pump I have. Seems to work well other than it does stall on occasion,(3-4 times on each job I'd say) But that seems to be a quirk with shutting these pumps on and off. But from the advice of others from around the boards I have added an oiler for this coming year. I think that may help with the shuttle valve sticking problem. I rinse every time anyhow to cycle water through the reels and hose, so rinsing the pump is just part of that. I would rinse a Kynar pump also. But definitely add the oiler. That stalling issue sucks. But I do like the the chemical resiliency of the pump. For the cost I think they're well worth it, even with the stalling issue,..better than dealing with performance dying and then having to change the pump. Dultmeirs also have these at a comparable cost to th one listed on E-bay. I think Dultmeirs shipping will be cheaper.

I think SOMETHING is wrong with the roof cleaning pump ?
No way our roof cleaners will be able to use a pump like that.
That would mean our ground man would have to take his attention off our customers property, and restart the roof cleaning pump.
We went away from TSP, until we got a strainer.
Experience has shown particles can get into the pump, and make it stall.
This is true with any pump.
All it takes is a small particle to unseat the valves, and a no spray condition occurs.
Our roof cleaning pumps stall once in a blue moon, and we simply re set the button and they are usually good to go for another week.
I would call Yamada Jeff, talk with them, see what they think ?
Are you pulling out of the top of your tank ?
If so, it is very important to keep the pump as close to the tank as possible, and the feed hose as short, and air tight as possible.
Even a SLIGHT leak in the feed line will piss away suction.
It is also important to know there are 2 kinds of valves these pumps come with, a flat one, and a round one.
Memory escapes me at the moment, but one type of valve has MORE suction lift then the other.
We use the Yamadaroof cleaning pump with the MOST suctionlift.
At any rate, Yamadais a GREAT Company, and Dave at Yamada in customer service will assist you any way he can.
Yamada pumps are MADE for "weird applications" like roofcleaning.
Far too often, with other" wanna be roof cleaning pumps" we heard "Well, what do you expect, you are shooting bleach" !!!
Yamada is used to people running acid and all kinds of nasty chit through their pumps.

Thanks Chris, I will be pulling from the top of the tank this year. I hooked up the pump the other day after an oiling and then the addition of the oiler in the air line. It worked with no stalling working the valve off and on for about 1/2 hour. Yea, I kinda' wondered about the pump having a defect as well, becasue it's done it since day one. But figure I will do some changing before I say it's the pump. Actually considering buying another one. But I also have the roller pump plumbed in also, and I can at least always have a back up.

Is is always good to have a back up roof cleaning pump.
Non Pressure Roof Cleaningas we know uses chemicals that are hard on pumps.
Never know when a roof cleaning pump will fail.
They usually go when you least expect them to.
A back up pump is always a good idea for any serious roof cleaner.

Jeff, did the oiler fix the problem or do you think it is a defect?

Just wondering.

Great idea Chris. I always carry an extra EVERYTHING in the trailer when cleaning roofs in Cleveland and Columbus Ohio. Extra pump, clamps, battery, hose, basically if everything went out at once im still good to go. I do NOT want to stop cleaning half way through a house because something broke and I dont have an extra.

Smart Move Guys,

I agree with you all wholeheartedly. When we clean roofs and perform other services here in Thomasville, GA and in North Florida Big Bend areas and Tallahassee,FL we try to always have, "A place for EVERYTHING and Everything in it's PLACE".

A backup, for my back up, is how I have run for a cleaning operation that is a non-issue. Extra parts mean less downtime.

I don't like breakdowns and backup parts and equipment figured into every job don't cost, it PAYS! Set aside 10% or even 5% and put into an "equipment fund". Disaster strikes when LEAST expected. Be PREPARED.

My Motto is " Fail to Plan, Plan to FAIL.

I plan to Succeed most of the time, but that wisdom has only come from a lot of past failures.

I like to call the past equipment breakdowns and jobsite problems- AFGO's which stands for "Another F*%^ing Growth Opportunity".

I and am glad you all work that way too, Smart and prepared.

It's the Smarter way and keeps the Tylenol bottle full . Less Headaches.

Man, do I absolutely not like it when I have to pull off a job for an o-ring or fitting or other small thing that I don't have or didn't buy a replacement for.

I try to make a take off list after and even during jobs and write down on a form any and all parts used and chemicals consumed along with Fuel expenses and any maintenance performed.

I helps me keep up with it all.

You hit the nail on the head. It will work BUT it is not KYNAR and will break down over time and will need to be rebuilt more often until it fails completely eventually.

Kynar is the way to go. Pretty much impervious to the Chemicals we Roof Cleaners Spray but the downside, KYNAR is expensive and pumps made from it are a King's Ransom.

To say that buying a Poly Pump on ebay or finding another great deal on one of these NDP-15's and using it until failure and in the meantime scouting for another new or used Poly mopdel as a backup and then getting a couple of rebuild kits and being prepared is better or worse, monetarily or from a downtime perspective is a tough call.

Six of one, half a dozen of the other??? Depends on who you are, what's important and priorities and how an individual thinks, plans and conducts business.

Bottom line is that it is Basically, the same pump in POLY (for a lot less) than many are paying 1,100.00-1,500.00 for in Kynar.

Just my rant and rave on the topic.

I have done better with Ryan/Herco, they have reps, and you can lie to them to get them down in price.
I would call Yamada, get a list of their reps, play one against the other!
Shop shop shop, get the BEST price!

I'm lookin at buying a roof cleaning pump, ( just starting out ), and noticed a gas powered chemical pump in the Northern catalog, powered bya 148cc Briggs + Stratton. It has a thermoplastic pump with EPDM seals. It builds to 44 psi, + can pump up to
8700 GPH. It sells for $ 250.00. Would this work for a starter operation ? It seems that it would be more practical than a 12 volt pump. It is rated at a max. head of 100 feet, + is manufactured by Pacer.

I hate to say no, but NO.
Post a link to it if you want, but seldom do any of these pumps work out for roof cleaning.
Most guys here start out with a Delavan 5800 series Roof Cleaning Pump.
It is a 12 volt pump,, runs off a deep cycle marine battery.
Suggest you read the dual Delavans thread here, lot to be learned about roof cleaning pumps!
The TRICK to top performance is yo use at least 5/8 or 3/4 hose with these 12 volt roof cleaningpumps

That's the reasoning I used when I bought mine. Used ity all last year (3-4) a week for 7 months. Still holding up well.

I have the 5 kynar and the 15 polyYamada and I love them both. I use a roll air compressor to feed them. I use the kynar to fill the mix tank and the poly 15 to shoot the roof. The 5 is all a small residential cleaner would need. I asked my wife if the yamada's could sleep with usI love them so much. She said no, something about wetting the bed.
